The Heritage Foundation and American Enterprise Institute will host their first-ever presidential debate tonight at 8 p.m. ET on CNN. Over the past few days, workers transformed an empty auditorium at Constitution Hall into a full-scale television set. As the final preparations were made, watch our behind-the-scenes look at how it all came together.

Featuring interviews with CNN’s Wolf Blitzer, who will moderate tonight’s debate; Kate Lunger, senior executive producer for CNN Special Events; Sam Feist, CNN’s Washington bureau chief; Keith Thornhill, debate project manager, and our own Edwin J. Feulner, president of The Heritage Foundation.

The video runs about 3:30. Produced by Brandon Stewart with the help of Rob Bluey. For more videos from Heritage, subscribe to our YouTube channel.
